Dual Fiber Bidirectional Transmission Mode
The wavelength of MUX and DEMUX is the same

Lower insertion loss

Lower insertion loss makes DWDM 19" rack
have lower signal attenuation in operation,
thus reducing the power requirement of
signal transmitter.

Higher isolation

The higher isolation value enables sufficient signal
isolation during multi-signal transmission in the
DWDM 19" rack, effectively preventing crosstalk
between signals and causing distortion of the transmission signal.

Mature production technology

The DWDM MUX&DEMUX 19" rack of FOCC has mature
production technology, stable and reliable performance,
supports the work in the harsh environment of - 40
~+85 ℃, and ensures the stable transmission of signals.

Application

DWDM MUX and DEMUX 19" 1U rack products have the characteristics of low insertion loss, low polarization, high channel isolation and high environmental stability and reliability, DWDM has 100 GHz, 200 GHz channel spacing, It is suitable for long-distance, large-capacity trunk network, or ultra-large capacity MAN core nodes, It is widely used in telecommunication 5G, MAN, backbone networks, data centers, etc.
